Resolution: Setting a lock scope prevents either threads or processes from writing over locked data. Lock scope is defined in the space definition properties. The lock scope value can be one of the following.
NONE - Specifies that locks do not have a scope.
THREAD - Specifies that threads cannot write over data that is locked by another thread.
PROCESS - Specifies that processes cannot write over data that is locked by another process. However, threads within the same process can overwrite data locked by another thread in the process.
